NOVELTY - The utility model claims a device for preparing graphene cathode material of lithium ion battery, comprising a base, the bottom of said pedestal is fixedly connected with a plurality of supports, wall outer side of the base is fixedly connected with a first electric machine, and the output end of the first motor is fixedly connected with the first rotating shaft. This utility model through the action of the second motor and the second rotating shaft to make the grinding roller drying the epoxy resin after the mixture of the citric acid and the alcohol solvent for grinding, and grinding the carbon micro-sphere will through the feed opening into the base; then finishing carbon microsphere and rotation of the first rotating shaft by first electric machine, mixing polyvinyl alcohol and acetone so as to greatly accelerate the production speed of graphene battery cathode material, besides through the cooperation of the connecting mechanism and bolt convenient to clean the base; so it is convenient for people when the emergency of the mixing and grinding process in other process.
